2. Set the time to 12:00 PM on March 20, 2024:
sudo hwclock --set --date "2024-03-20 12:00:00"
3. Synchronize the RTC time to the system:
sudo hwclock --hctosys
4. Check the RTC time:
sudo hwclock -r
This command will read and display the time stored in the RTC.
5. Disconnect the power source from the RTC, wait a few minutes, then reconnect it and check the RTC time again
to see if it retained the correct time.
3.14 Watchdog
To perform a watchdog test, follow these steps:
1. Install the watchdog software:
sudo apt install watchdog
2. Edit the watchdog configuration file:
# make sure you install vim already, if haven't, can install by the command below
sudo apt-get install vim
sudo vim /etc/watchdog.conf
Modify the configuration as follows:
watchdog-device= /dev/watchdog
# Uncomment and edit this line for hardware timeout values that differ
# from the default of one minute.
watchdog-timeout = 120
# If your watchdog trips by itself when the first timeout interval
# elapses then try uncommenting the line below and changing the
# value to 'yes'.
#watchdog-refresh-use-settimeout = auto
# If you have a buggy watchdog device (e.g. some IPMI implementations)
# try uncommenting this line and setting it to 'yes'.
#watchdog-refresh-ignore-errors = no
# ====================== Other system settings ========================
#
# Interval between tests. Should be a couple of seconds shorter than
# the hardware time-out value.
interval= 15
max-load-1 = 24
#max-load-5= 18
